Description
1.Product Introduction
LSH10-1A open channel flowmeter adopts the principle of ultrasonic “doppler effect” to measure the flow velocity.With the use of ultrasonic technique to detect the flow velocity, the flow rate of sampling point is in front of device 20cm and not to demage the flow field.It is the best channel device with high accuracy, linear measurement, instantaneous velocity, average velocity, no rotating components, particularly suitable for use in sediment blockage and seaweed floating particles wrapped, It is durable and reliable and simple for use.
2.Performance Characterristics
1、High accuracy,wider range, week flow speed and high flow speed can be measured.
2、High sensitive,high resolution,without startup velocity limitation.
3、Fast speed response,the instantaneous velocity and average velocity can be measured.
4、Linear measurement,without calibrating the curves of K and C parameters.
5、Without mechanical rotating components, particularly suitable for use in sediment blockage and seaweed floating particles wrapped and frozen circumstance environments.
3.Function introduction
1、Host computer Mini design is convenient for users to caryy and work.
2、Large screen LED has the continuous backlighting function.
3、Internal chock is convenient for users to calibrate and inquery the time
4、Reading data from the software we attached to store data, print data and output data.
5、Real time display of the instantaneous and average flow velocity and flow rate.
6、Automatic and manual measurement can meet the needs of the different occasions.
